Description

Die Erfindung bezieht sich auf eine Anschlußleiste der Fernmeldetechnik, gemäß dem Oberbegriff des Anspruches 1.The invention relates to a terminal block of telecommunications technology, according to the preamble of claim 1.

Eine Anschlußleiste der gattungsgemäßen Art ist aus der DE-PS 28 04 478 vorbekannt. Diese besteht aus einer Trägerplatte und aus einem auf die Träger­platte aufrastbaren Oberteil. Trägerplatte und Ober­teil sind aus Kunststoff hergestellt. In die Träger­platte sind mehrere Anschlußelemente mit jeweils zwei Schneid-Klemmkontakten einsteckbar, die in das Ober­teil hineinragen. Das Oberteil besitzt an seiner Gehäuseoberseite mehrer Klemmelemente mit dazwischen­liegenden schlitzförmigen Öffnungen. Die Schneid-Klemm­kontakte bestehen jeweils aus zwei blattförmigen fe­dernden Kontaktschenkeln, zwischen denen ein Kontakt­schlitz gebildet wird. Der nach oben offene Kontakt­schlitz des in der Anschlußleiste eingebetteten Schneid-Klemmkontaktes ist von oben zugänglich, auf­grund der schlitzförmigen Öffnung des Oberteiles. Da sehr enge Toleranzen zwischen der Trägerplatte und dem auf­rastbaren Oberteil eingehalten werden müssen, sind nur Anschlußleisten kleiner Längen mit vertretbarem tech­nischem Fertigungsaufwand herstellbar, da sich bei größeren Längen eventuelle Toleranzabweichungen addieren. Darüber hinaus sind die Herstellungskosten sehr langer Oberteile für Anschlußleisten aufgrund der erforderlichen großen Spritzgußwerkzeuge sehr hoch.A terminal block of the generic type is previously known from DE-PS 28 04 478. This consists of a carrier plate and an upper part that can be snapped onto the carrier plate. Carrier plate and upper part are made of plastic. A plurality of connection elements, each with two insulation displacement contacts, can be inserted into the carrier plate and protrude into the upper part. The upper part has several clamping elements on its upper side of the housing with slot-shaped openings in between. The insulation displacement contacts each consist of two leaf-shaped resilient contact legs, between which a contact slot is formed. The open top contact slot of the insulation displacement contact embedded in the terminal block is accessible from above, due to the slot-shaped opening of the upper part. Since very tight tolerances between the carrier plate and the snap-on top part have to be observed, only terminal strips of small lengths can be produced with reasonable technical production effort, since tolerance deviations add up with longer lengths. In addition, the manufacturing costs of very long top parts for terminal strips are very high due to the large injection molding tools required.

Nach DE-PS 28 11 812 werden daher Anschlußleisten mit kleinen Längen, die zehn Doppeladeranschlüsse (10 DA) aufweisen, auf einen Montagebügel aufgerastet.According to DE-PS 28 11 812 terminal strips with small lengths, which have ten double wire connections (10 pairs), are snapped onto a mounting bracket.

Der Erfindung liegt von daher die Aufgabe zugrunde, eine Anschlußleiste der gattungsgemäßen Art zu schaffen, die eine größere Länge besitzt und daher mehr als 10 DA aufnehmen kann, ohne daß die Gefahr der Addition von Toleranzfehlern besteht und ohne daß der Fertigungsauf­wand erhöht wird.The invention is therefore based on the object to provide a terminal block of the generic type, which has a greater length and can therefore accommodate more than 10 pairs, without the risk of addition of tolerance errors and without increasing the production costs.

Die Lösung dieser Aufgabe ergibt sich aus den kennzeich­nenden Merkmalen des Anspruches 1. Erfindungsgemäß werden die Toleranzwerte einer längeren Anschlußleiste nur auf eine Teilleiste bezogen. Vorteilhaft läßt sich die Anschlußleiste fertigungstechnisch kostengünstig herstellen, da für die Herstellung der Teilleisten nur kleine Spritzgußwerkzeuge benötigt werden.The solution to this problem results from the characterizing features of claim 1. According to the invention, the tolerance values of a longer terminal block are only related to a partial bar. The terminal block can advantageously be produced at low cost in terms of production technology, since only small injection molding tools are required for the production of the partial strips.

Weitere vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen. So können auch zwei Reihen von Teilleisten nebeneinander auf einer Trägerplatte angeordnet sein, wobei eine gemeinsame Erdschiene für den Erdanschluß dient.Further advantageous embodiments of the invention result from the subclaims. Two rows of partial strips can also be arranged next to one another on a carrier plate, with a common earth rail serving for the earth connection.

Die Erfindung ist nachfolgend anhand eines in den Zeichnungen dargestellten Ausführungsbeispieles einer Anschlußleiste näher erläutert. Es zeigt:

  • Fig. 1 eine Perspektivansicht der Anschlußleiste,
  • Fig. 2 einen Querschnitt durch die Anschlußleiste und
  • Fig. 3 eine Draufsicht auf die Trägerplatte der Anschlußleiste mit teilweiser Darstellung zweier Teilleisten.

Carrier plate 1 and part strips 3 to 7 are made of plastic. The part strips 3 to 7 are identical to the upper parts according to DE-PS 28 04 478.

Die Trägerplatte 1 besitzt mehrere, in zwei Reihen hintereinander angeordnete Aufnahmekammern 8 bis 12 für die jeweiligen Teilleisten 3 bis 7. In jeder Auf­nahmekammer 8 bis 12 sind mehrere Querwände 19 vor­gesehen, welche die Aufnahmekammern 8 bis 12 wiederum in mehrere einzelne Teilkammern 20 zur Aufnahme von Anschlußelementen 23 unterteilen. In den sich dia­gonal gegenüberliegenden Ecken jeder Teilkammer 20 sind zwei Aufnahmeschlitze 24 für Schneid-Klemm­kontakte 22 eingearbeitet. Die Anschlußelemente 23, die jeweils zwei zur Querachse unter 45° stehende Schneid-­Klemmkontakte 22 aufweisen, sind aufrecht stehend in die Teilkammern 20 eingesteckt, wobei jeweils ein Kon­taktschenkel 21 der beiden Schneid-Klemmkontakte 22 eines Anschlußelementes 23 im Aufnahmeschlitz 24 klemmend gehalten ist. In den zehn Teilkammern 20 einer Aufnahmekammer 8 bis 12 sind somit zehn An­schlußelemente 23 für fünf Doppeladern aufgenommen. In Fig. 3 sind in der linken Aufnahmekammer 8 drei Teil­kammern 20 gezeigt. Die Aufnahmekammern 8 bis 12 sind insoweit identisch mit den Unterteilen nach DE-PS 28 04 478 ausgebildet.The carrier plate 1 has a plurality of receiving chambers 8 to 12, arranged one behind the other in two rows, for the respective partial strips 3 to 7. In each receiving chamber 8 to 12, a plurality of transverse walls 19 are provided, which in turn the receiving chambers 8 to 12 into a plurality of individual partial chambers 20 for receiving Subdivide connection elements 23. Two receiving slots 24 for insulation displacement contacts 22 are incorporated in the diagonally opposite corners of each partial chamber 20. The connection elements 23, which each have two insulation displacement contacts 22 at 45 ° to the transverse axis, are inserted upright into the subchambers 20, with one contact leg 21 of the two insulation displacement contacts 22 of a connection element 23 being held in the receiving slot 24 in a clamping manner. In the ten subchambers 20 of a receiving chamber 8 to 12, ten connection elements 23 for five double wires are thus received. In Fig. 3 three sub-chambers 20 are shown in the left receiving chamber 8. The receiving chambers 8 to 12 are so far identical to the lower parts according to DE-PS 28 04 478.

Auf die aufrecht stehenden Anschlußelemente 23 einer Aufnahmekammer 8 bis 12 ist eine Teilleiste 3 bis 7 aufgeschoben. Im Gehäuseinneren der Teil­ leiste 3 bis 7 sind ebenfalls mehrere, durch Quer­wände 19′ getrennte, mit Aufnahmeschlitzen 24′ ver­sehene Teilkammern 20′ vorgesehen. Vier außen an der äußeren Wandung 16 der Aufnahmekammern 8 bis 12 vorge­sehenen Rastsegmente 18 rasten in Rastvertiefungen 17 der Wandung der Teilleisten 3 bis 7 ein.A partial strip 3 to 7 is pushed onto the upright connection elements 23 of a receiving chamber 8 to 12. Inside the part bar 3 to 7 are also several, by transverse walls 19 'separate, with receiving slots 24' provided partial chambers 20 'is provided. Four latching segments 18 provided on the outside of the outer wall 16 of the receiving chambers 8 to 12 snap into latching depressions 17 of the wall of the partial strips 3 to 7.

Fünf Teilleisten 3 bis 7 mit je fünf Doppeladeranschlüssen sind in jeder der beiden Reihen hintereinander auf der Trägerplatte 1 zur Bildung der Anschlußleiste auf­gerastet, die somit insgesamt 50 Doppeladeranschlüsse umfaßt.Five sub-strips 3 to 7, each with five double-core connections, are snapped in place in each of the two rows on the carrier plate 1 to form the terminal strip, which thus comprises a total of 50 double-core connections.

An der Oberseite 25 der Teilleiste 3 bis 7 sind Klemmelemente 26 mit dazwischenliegenden Klemm­schlitzen 27 für die Kabeladern 28 vorgesehen. Durch den Klemmschlitz 27 ist jeweils ein nach oben offener Kontaktschlitz 41 des Schneid-Klemmkontaktes 22 von oben zugänglich. Zum Anschluß einer isolierten Kabel­ader 28 an das Anschlußelement 23 wird die Kabelader 28 zuerst in den Klemmschlitz 27 eingelegt und dann mit Hilfe eines nicht dargestellten Werkzeuges in den Kontaktschlitz 41 des Schneid-Klemmkontaktes 2 eingedrückt, wobei die den Kontaktschlitz 41 be­grenzenden scharfen Kanten der unter 45° zur Quer­achse stehenden Kontaktschenkel 21 zuerst die Isola­tion durchschneiden und dann in den leitenden Kern der Kabelader 28 eindringen. Die Anschlußelemente 23 besitzen mittig entweder einen Abgriff 38 oder einen Trennkontakt 40, Fig. 2.Clamping elements 26 with clamping slots 27 in between for the cable cores 28 are provided on the upper side 25 of the partial strip 3 to 7. Through the clamping slot 27, an upwardly open contact slot 41 of the insulation displacement contact 22 is accessible from above. To connect an insulated cable wire 28 to the connecting element 23, the cable wire 28 is first inserted into the clamping slot 27 and then pressed into the contact slot 41 of the insulation displacement contact 2 using a tool (not shown), the sharp edges of the contact slot 41 delimiting the contact slot 41 ° to the transverse axis contact leg 21 first cut through the insulation and then penetrate into the conductive core of the cable core 28. The connecting elements 23 have either a tap 38 in the center or a disconnecting contact 40, FIG. 2.

Wie es in den Figuren 1 und 2 dargestellt ist, sind zwei Reihen von Teilleisten 3 bis 7 parallel zuein­ander auf der Trägerplatte 1 montiert. Zwischen den beiden Reihen ist in der Tägerplatte 1 eine parallel zu den Reihen verlaufende Nut 13 vorgesehen, in die eine metallische Erdschiene 14 eingesteckt ist. Die Erdschiene 14 ist beidseitig von die Nut 13 begren­zenden Kunststoffwänden 31, 32 berührungssicher in der Trägerplatte 1 gelagert. Die Erdschiene 14 ist mit einem nicht dargestellten Erdpotential verbunden und dient als Erdabgriff für die in die Teilleisten 3 bis 7 einsteckbaren Überspannungsableiter-Stecker 29, die hierzu einen Gabelkontakt 30 aufweisen, der auf die Erdschiene 14 aufgesteckt ist. Im Inneren des Gehäuses jedes Steckers 29 ist ein 3-Pol-Überspan­nungsableiter 34 angeordnet, dessen Mittelkontakt 35 mit dem Gabelkontakt 30 und dessen Außenkontakte 36, 37 über Kontaktzungen 39 jeweils mit einem mittleren Ab­griff 38 des Anschlußelementes 23 verbunden sind. Mit Hilfe eines Steckers 29 werden zwei an zwei An­schlußelementen 23 angeschlossene Kabeladern 28 im Überspannungsfall auf Erdpotential geschaltet.As shown in FIGS. 1 and 2, two rows of partial strips 3 to 7 are mounted parallel to one another on the carrier plate 1. Between In both rows, a groove 13 running parallel to the rows is provided in the carrier plate 1, into which a metallic earth rail 14 is inserted. The earth rail 14 is supported on both sides by plastic walls 31, 32 delimiting the groove 13 in a contact-safe manner in the carrier plate 1.
